Different Types of Concrete Grades and Their Uses

Whether you need a suitable concrete mix for a residential or commercial project or simply want to learn more about concrete grades, this guide will help you understand their differences and applications. Keep reading to explore various concrete types and their uses, or reach out to us for expert advice!

Types of Concrete Grades

Ordinary Concrete

M5, M7.5, M10, M15, M20

5–20 MPa

Used for non-structural applications, small residential buildings, pathways, and plain cement concrete works.

Low cement content

High water-cement ratio

Low durability

Easy to work with

Low cost

Light or no reinforcement

Longer setting time

Low crack resistance

Standard Concrete

M25, M30, M35, M40

25–40 MPa

Used for reinforced concrete structures, commercial buildings, bridges, roads, and industrial floors.

Moderate cement content

Moderate water-cement ratio

Medium durability

Moderate workability

Medium cost

Reinforced

Moderate setting time

Moderate crack resistance

High-Grade Concrete

M45, M50, M55, M60, M65, M70, M75, M80

45–80 MPa

Used for high-rise buildings, heavy-load structures, metro pillars, dams, and specialized infrastructure projects.

High cement content

Low water-cement ratio

High durability

Requires admixtures

High cost

Requires high-strength reinforcement

Shorter setting time (controlled curing)

High crack resistance (better shrinkage & thermal resistance)

Choosing the Right Concrete Grade

Selecting the appropriate concrete grade for your project depends on factors like structural load, stress levels, and environmental conditions. As per IS 456 standards, reinforced concrete structures should use at least M20 grade concrete. However, for projects with higher strength requirements, such as roads or industrial buildings, advanced concrete grades may be necessary.
